This commit adds driver support for PCI fast ethernet NICs based on

Browse Source 
the Davicom DM9100 and DM9102 chipsets, including the Jaton Corporation
XPressNet. Datasheet is available from www.davicom8.com.

The DM910x chips are still more tulip clones. The API is reproduced
pretty faithfully, unfortunately the performance is pretty bad. The
transmitter seems to have a lot of problems DMAing multi-fragment
packets. The only way to make it work reliably is to coalesce transmitted
packets into a single contiguous buffer. The Linux driver (written by
Davicom) actually does something similar to this. I can't recomment this
NIC as anything more than a "connectivity solution."

This driver uses newbus and miibus and is supported on both i386
and alpha platforms.

Davicom DM9100/DM9102 fast ethernet device driver
.Sh SYNOPSIS
.Cd "controller miibus0"
.Cd "device dm0"
.Sh DESCRIPTION
The
.Nm
driver provides support for PCI ethernet adapters and embedded
controllers based on the Davicom DM9100 and DM9102 PCI
fast ethernet controller chips including the Jaton Corporation
XPressNet.
.Pp
The DM9100 and DM9102 are designed to be DEC 21x4x workalikes. The
register layout, DMA descriptor scheme and receive filter programming
are identical to the DEC part. The DM9102
is a 100Mbps ethernet MAC and MII-compliant transceiver
in a single package. The DM9100 is similar to the DM9102 except
that it has no internal PHY, requiring instead an external transceiver
to be attached to its MII interface.
.Pp
The
.Nm
driver supports the following media types:
.Pp
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
.It autoselect
Enable autoselection of the media type and options.
The user can manually override
the autoselected mode by adding media options to the
.Pa /etc/rc.conf
fine.
.It 10baseT/UTP
Set 10Mbps operation. The
.Ar mediaopt
option can also be used to select either
.Ar full-duplex
or
.Ar half-duplex modes.
.It 100baseTX
Set 100Mbps (fast ethernet) operation. The
.Ar mediaopt
option can also be used to select either
.Ar full-duplex
or
.Ar half-duplex
modes.
.El
.Pp
The
.Nm
driver supports the following media options:
.Pp
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
.It full-duplex
Force full duplex operation
.It half-duplex
Force half duplex operation.
.El
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
.Sh DIAGNOSTICS
.Bl -diag
.It "dm%d: couldn't map ports/memory"
A fatal initialization error has occurred.
.It "dm%d: couldn't map interrupt"
A fatal initialization error has occurred.
.It "dm%d: watchdog timeout"
The device has stopped responding to the network, or there is a problem with
the network connection (cable).
.It "dm%d: no memory for rx list"
The driver failed to allocate an mbuf for the receiver ring.
.It "dm%d: no memory for tx list"
The driver failed to allocate an mbuf for the transmitter ring when
allocating a pad buffer or collapsing an mbuf chain into a cludmr.
.It "dm%d: chip is in D3 power state -- setting to D0"
This message applies only to adapters which support power
management. Some operating sydmms place the controller in low power
mode when shutting down, and some PCI BIOSes fail to bring the chip
out of this state before configuring it. The controller loses all of
its PCI configuration in the D3 state, so if the BIOS does not set
it back to full power mode in time, it won't be able to configure it
correctly. The driver tries to detect this condition and bring
the adapter back to the D0 (full power) state, but this may not be
enough to return the driver to a fully operational condition. If
you see this message at boot time and the driver fails to attach
the device as a network interface, you will have to perform second
warm boot to have the device properly configured.
.Pp
Note that this condition only occurs when warm booting from another
operating sydmm. If you power down your sydmm prior to booting
.Fx ,
the card should be configured correctly.
